ProdMod ™

By using an $11 DC-DC boost circuit in the Prodmod LED Camera Light I am now able to power it with one, two, or three batteries and can use either rechargeable or alkaline and still maintain a fixed LED brightness. The brightness of the LEDs remains unchanged until the very last moment when the total battery voltage drops below 1V. The flexibility of the DC-DC boost circuit allows you to use either one or two batteries if I wish leaving room for other items in the case. It also allows you to position your mount stud somewhere else if it better suits your camera.

I tested a 5V circuit and a 3.3V and compiled the results. There is an effect on battery life but its not as bad as you might think.

I have recently posted the LED Camera Light how to on instructables. It is a summarized version of the DIY on this site.

Please go check it out and if you like this DIY and like what I am doing please click the “” mark at the top of the instructables version and add it as a favorite to show your support.

This would be a great way for me to get the word out about the prodmod website. The more people contribute to this site the more ideas and projects can be discussed here.

I took a little break from making gadgets to go to this Fuerzabruta show in NYC. It’s standing room only in this very tall yet small black space and you get moved around as the contraptions and gadgets are moved around the area near you and above you. It’s basically like you are in the middle of someone elses crazy dream. There is an actor on a treadmill in front of you running as fast as he can with walls of paper boxes being hurled at him. There is wind generators, flying paper, treadmills and water. It was unique and interesting and I have to admit I was distracted by all the gadget to really absorb the art of the show except for the ladies of course.

I just want to show everyone that a 4LED camera light is possible using the same 4xAAA battery holder that comes in the DIY kit. So I am including the 4th LED in the kit and removing the screws since they are probably easy for you to find at your local hardware store. If you still need them you can add them to your cart.

If you don’t what what you are looking at, you can read the original DIY here, and watch a demo video to get an idea of what this light can do for your camera.

You can still use the 10 ohm resistor which will limit your current per LED to about 20mA. You can go higher by using a 8 ohm resistor giving you about 28mA to start, but I don’t have any of those on hand. I think 20mA x 4 LEDs will give more light and wider coverage than the 3LED version.

To accomplish the 4LED you just need to plan ahead and make some room. Read more »

As promised here is a video demonstration of how an unlit room can be illuminated with the LED Camera Light.

This light had 3 LEDs and freshly charged batteries.

My camera takes video in MOV format and when I upload to Youtube it gets really grainy and dark. If anyone know how to fix that let me know.

But as you can see 3LEDs light up pretty well and almost cover the entire viewing area. You could simply zoom in just a bit to get rid of any dark areas.

Sorry about the setting but the bathroom is the only place where I can truly close out all ambient lighting. So what you see here is only illuminated by the Camera Light.

In case you don’t know what the ProdMod Camera Light is you can read the DIY.

It only costs $2 if you find the parts yourself or you can buy the kit for $9.99.
